Product Description


WFCO’s WF-5110RS is the new and improved 1000-watt inverter in our product line. The new design reduces parasitic draw, while maximizing battery power and efficiency. Featuring automatically resettable Reverse Polarity protection, the WF-5110RS is protected from permanent damage should a battery be connected backwards. Once the battery connections are corrected, the unit will operate normally. The WF-5110RS also has an exclusive internal transfer system which automatically allows the AC input to bypass the inverter when the inverter is connected to an AC power source. WFCO’s WF-5110RS improved upon the same reliable inverter that customers have come to love, with the added benefit of a longer lasting battery that customers need.

Additionally, the WF-5110RS provides high-efficiency power at full-load conditions with safeguards that include overload protection, over-temperature protection, and short-circuit protection. The cooling fan enhances efficiency as its operation is controlled by the amount of load incurred by the inverter. FCC Class B compliance, which means that the inverter is designed not to cause interference with televisions, radios, or other signals.
